Expanding stellar associations as Galactic accelerometers

Till Sawala, Núria Miret Roig

The gravitational potential of the Milky Way is fundamental for understanding the evolution of our Galaxy and the nature of dark matter. We introduce a new method to constrain the…

Discovery of an Unbound Flyby Companion of UBC 63: In the Immediate Aftermath of a Close Encounter

Samrat Biswas, Biman J Medhi, Sergio Messina +8

We re-investigate the open cluster UBC 63 using the Gaia DR3 data and show that, rather than being a single cluster as previously classified, it is a compelling candidate for a dou…

Random gas motions inside sub-parsec scale supercritical filaments

Chao Zhang, Tie Liu, Mika Juvela +12

Supercritical gas filaments in molecular clouds host the dense cores in which new stars form. The mechanisms governing their formation and subsequent gas accretion remain poorly un…

Detection of C Combination Bands in the Near-IR Spectrum of Tc 1

Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26

We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying th…

A new Gaia census of OB associations within 1 kpc

Alexis L. Quintana, Nicholas J. Wright, Lilly A. Kormann +6

OB associations are primordial tracers of star formation and Galactic structure. Originally defined about 80 years ago, their historical membership lists have been superseded thank…

GASTRO library II: Exploring Chemical Bimodalities in Disk Galaxies with GSE-like Mergers and Massive Star-forming Clumps

João A. S. Amarante, Chervin F. P. Laporte, Victor P. Debattista +10

We use several smoothed particle hydrodynamics+N-body models as part of the GASTRO library to study the role of high-density star-forming clumpy regions and a single merger on the…
